I built a monstrous password cracking setup using Docker and Salad Cloud - 31 x RTX 4090s running hashcat connected to Hashtopolis - and wanted to share the experience with everyone! This is the largest 4090 hashcat cluster I've seen posted on the internet - beating out Kevin Mitnick's current setup - but I'd love to hear if there are larger clusters out there. I'm not affiliated with Salad Cloud in any way, but as a cybersecurity researcher I wanted to find a way to quickly scale up / scale down a password cracking service without renting servers individually on service like vast.ai.
SaladCat is the name of the Docker container and some automation code that I used to pull off - I've open-sourced all of the code and Docker containers used in this project.
